Step by Step
- Open File Explorer or the relevant Windows storage/cloud settings.
- A file extension helps Windows and applications identify the file's format and which program should open it.
- Verify the file location and result before deleting an original or emptying Recycle Bin.
- Keep a separate backup of important files, especially before reorganizing or freeing substantial storage.
If That Doesn't Work
- Cloud-synchronized folders can behave differently from ordinary local folders; confirm synchronization status before deleting files.
- Avoid deleting unfamiliar Windows or application files simply because they are large.
